tending lengthwise of the pen barrel to-A gether with a barextendingalong the reservoir :tor the purpose ot collapsing the same in filling,and means Jfor returning the bar to its normal position after it hasbeen relieved ot pressure. Such devices have, however,

been cumbersome or unsatisfactory for various reasons.

rllie object of my invention is to provide an improved and muchsimplified construction which is separate trom the rest ot the pen andreadily removable and replaceable. To this end l make the presser barand its support a distinct structure removable to gether, the supportbeing retained frictionally and removably in position. rlhe simplest andbest support for this purpose is a sheet metal collar which by itstendency to expand retains itself in place. -ll prefer to so constructthis support that it will move `down as a Whole when pressure is appliedto the presser bar and will assist the return ot the same by springingbaclr into place when pressure is removed. l prefer to use a pluralityot collars having a common tongue.

Edy invention therefore consists in the subject matter describedin thespecification and more particularly pointed vout in the appended claims.

Referring to the accompanying drawings: Figure l is a top plan view oitthe pen showing parts of the outer casing in section, one part thereofbeing slipped to one side as is donewhen the pen isl to be iilled. Fig.2 is aside elevation and section similar to Fig. l. Fig. 3 is a crosssection on line 3--3, Fig. l. Fig.Y t inner tubular casing. Fig. 5 is anenlarged plan view of the yblank from which the presser bar su port isformed and of the presser bar. Fig. 6 is a perspective view of thepresser bar and its support. Fig. 7 is a side elevation and sectionsimilar to Fig. 2 but showing the preferred-'form ot support the partsbeing in the position they assume in which it has been customp is aperspective view ot the when the ink reservoir is partially collapsed.Fig. 8 is an enlarged plan view of the blank from which the referredform of support is made. Fig. 9 is a perspective view of the presser bartogether with the preferred form of support.

ln the pen, as thusv illustrated, 1 is the usual nozzle; 2 is a part ofthe outer tubular casino1 or barrel; and 3 another part which may bemoved into or out of contact therewith. 1vlithin this outer casing, lhave shown a tubular inner casing 4 providedA with a cut out oi slot 5and inclosing the flexible ink reservoir 6 which runs lengthwise of thepen.

7 is the usual presser bar accessible through the slot 5 when the partsof the outer casing are separated so that the pen may be filled. Inaccordance with my inlvention'the bar is part of a distinct structurewhich is removable as a whole from the rest of the pen. The part of thisstructure constituting the support for the bar have illustrated as aspring collar 8 formed trom a sheet metal blank 9 (see Fig. 5) having atongue 10 extending lengthwise of the pen and to which the -presser baris secured. The material for this collar is preferably sheet steel togive it the' requisite strength and elasticity. lThe part of the blankdesigned to torni the collar is bent into tubular form to lit the boreot the casing within which it is to be placed, the collar by 'virtue ot'its tendency to expand retaining itselt and the presser bar in positiontrictionally and removably in the casing. l prefer to employ an innercasing and' to locate the spring collar in the open end thereof.

.l rind it advantageous to make the sup- .port tor the presser bar insuolil `a manner that the entire support as well as the longitudinaltongue will yield when pressure is applied to depress the presser barand will, by its spring action, assist in returning the bar to itslnormal position. rThis l iind is` accomplished by separating the endsot the collar so that the entire collarl may move downward and springback again when pressure is removed.

The above description hasdealt more particularly with the constructionillustrated in Figs. 143. It remains to describe the pre- 'l'erred formof support tor the presser bar as illustrated in the remaining figures.

Ihave round that by providing a plurality of spring supports with acommon tongue, to which the presser bar is secured, the motion sure isremoved.

'v :'.Referringto Figs. 7lthe noz'zle 1, outer" casing parts 2 and 3,inner'y casing 4, slot 5,

, collapsible ink reservoir 6 and presser bar 7 are the same as thecorresponding arts in the other ures'.- The support gor the presser barhowever, is formed from -a double blank T9 of sheet metal (see Fig. 8)Awhose vends are connectedby the common tongue '10fthe said ends beingbent to form spring collars 8', 8. l I prefer to secure the presser bar7 to the tongue 10 `midway between the collars'8, S', and to locate thepoint of connection dat the middle of the presser bar 7. The action ismore even and accurate when this 1s done.

It will be evident that my inventionv has jv thev meritsof extremesimplicity, economy What I claim as my casing, a' flexible inkreservoirlextending lengthwise of. the pen in saidi casing, a presserbarextending along saidreservoir,
